We hypothesized that plasma-based EGFR mutation analysis for NSCLC may be feasible for monitoring treatment response to EGFR TKIs and also predict drug resistance.Clinically relevant mutations including exon 19 deletion (ex19del), L858R and T790M were analyzed using droplet digital PCR (ddPCR) in longitudinally collected plasma samples (n = 367) from 81(More)
Image fusion deals with the integration of remote sensing images from various sensors, with multi-spectrum and high-spectrum, multi-angle viewing and multi-resolutions, aiming at achieving improved image quality to better support improved image classification, monitoring and etc. The main goal of this paper is to introduce a new approach to fuse(More)

INSAR(Interferometric Synthetic Aperture Radar) has been studied and used widely in the field of generating high accuracy DEM(Digital Elevation Model). The processing of INSAR includes many key technologies, such as image matching, phase unwrapping, baseline estimation, etc. The phase unwrapping is difficult, but it can be made easy and simple by an(More)
X-ray Fluorescence Computed Tomography(XFCT) is a prevalent experimental technique which is utilized to investigate the spatial d istribution of elements in sample. The sensitivity of L-shell XFCT of some elements is lower than that of K-shell XFCT. However, the image reconstruction for this technique has much more problems than that of transmission(More)
The video retrieval system we developed for TRECVID 2012 mainly involves the semantic indexing task which includes key frame extraction, low level feature extraction, classification and concept fusion. We extracted a new low level feature, explored various classification and fusion schemes. Four " light " runs and two 2 " pair " runs we submitted are as(More)
